Hi everyone
The Timber Guide approves 118x180 GL30cs with a free span of 4m, which is the depth of the deck.
Now I intend to use 118x180 impregnated ntr A glulam beam GL28h classified and it is missing in the timber guide's app for dimensioning help.
Question: Can a GL28h also handle a 4m free span equivalent to GL30cs?
Grateful for help
